Targeted Lenovo ThinkPad Upgrade

This 16 GB kit contains two 8 GB DDR4 SO-DIMMs rated at 2400 MHz with CL17 timings. The modules run at 1.2 V, are unbuffered, non-ECC and use a 260-pin layout. They are built specifically for ThinkPad P50, P51, P70 and P71 mobile workstations.

Not for Other Laptops or Desktops

The SO-DIMM form factor and validated compatibility list restrict use to the named ThinkPad models. Systems requiring ECC, registered DIMMs, a different pin count or higher speed grades will not accept these modules. Buyers needing more than 64 GB total capacity or a different memory generation should look elsewhere.

2400 MHz DDR4 Speed Decides Fit

The platform memory controller must support DDR4-2400 (PC4-19200) operation for the kit to run at its rated frequency. If the laptop BIOS locks memory to a lower speed, the modules will downclock automatically. Verify the 2400 MHz specification against the service manual before purchase.

Questions about this item

What comes in the box and is anything else required for installation?

The package includes two 8 GB DDR4 SODIMM sticks, giving 16 GB total. No extra parts or tools are needed beyond a compatible ThinkPad slot.

Should I choose the 16 GB kit or a different capacity for my ThinkPad P50, P51, P70 or P71?

This 16 GB kit fills two of the four available slots. The platform supports up to 64 GB, so you can add another identical kit later if you need more memory.

What does the 2400 MHz rating mean once the modules are installed in my laptop?

The memory will run at 2400 MHz with CL17 timing at 1.2 V, delivering PC4-19200 bandwidth in the supported ThinkPad models.
